For many Medicare beneficiaries, the most important question this fall is not whether their health plan has a $0 premium. It is whether the plan will still let them see the doctors, use the pharmacies and receive the treatments that keep their lives stable.
Medicare’s annual open-enrollment period runs from October 15 through December 7, 2026, with changes taking effect January 1, 2027. This year, millions of people are being asked to reconsider coverage because private Medicare plans are ending, consolidating or changing their costs and benefits.
A KFF analysis of Medicare plan data estimates that 4.3 million beneficiaries are in Medicare Advantage prescription-drug plans or stand-alone Part D plans that will be terminated at the end of 2026. About 3.1 million of them are in Medicare Advantage drug plans, while roughly 1.2 million are in stand-alone prescription plans.
Another 1.4 million Medicare Advantage enrollees are in plans being consolidated into another plan offered by the same insurer. Those beneficiaries are expected to be moved automatically, but automatic reassignment does not mean that the replacement plan has the same doctors, hospitals, drug formulary or supplemental benefits.
A plan can look similar and work very differently
Medicare beneficiaries are routinely told to compare plans. That advice is reasonable, but it understates the work involved.
A meaningful comparison may require checking whether an oncologist, cardiologist, dialysis center, rehabilitation provider, hospital, laboratory and imaging facility remain in network. It may require comparing every recurring prescription against a new formulary, identifying preferred pharmacies and reviewing prior-authorization rules. It may also require examining the maximum out-of-pocket limit, deductibles, copayments and the rules governing dental, transportation, food or over-the-counter benefits.
Medicare’s 2027 guide tells beneficiaries to review changes in costs and coverage rather than automatically renewing. That is good advice. But a comparison tool cannot eliminate the underlying problem: the person doing the comparison may be sick, elderly, disabled, cognitively impaired or caring for someone who is.
For a healthy beneficiary with few prescriptions, switching plans may be manageable. For a person receiving cancer treatment or managing dementia, diabetes, kidney disease or multiple disabilities, changing coverage can mean rebuilding a care network one phone call at a time.
The unpaid labor of “choice”
Medicare formally addresses the beneficiary. In practice, the work often falls to a spouse, adult child or other caregiver.
That person may read the annual notice, search provider directories, call physicians’ offices, confirm medications, compare pharmacy arrangements and help complete enrollment forms before the deadline. If the plan changes after January 1, the caregiver may also be the person who discovers that a prescription requires a new authorization or that a familiar specialist is no longer covered.
This is one of the less visible costs of a market built around annual plan choice. The system treats comparison as a consumer task, but the people making the decision are often managing illness, transportation, work schedules and family responsibilities at the same time.
The burden is particularly serious for beneficiaries under 65 who qualify for Medicare because of disability, for people who are dually eligible for Medicare and Medicaid, and for rural residents with fewer nearby specialists and hospitals.
More plans do not necessarily mean more usable choice
CMS says Medicare Advantage remains broadly available in 2027: more than 99% of beneficiaries are expected to have access to at least one Medicare Advantage plan, and 97% are expected to have access to at least 10. The agency also projects that total plan availability will remain relatively stable.
Those figures describe formal availability. They do not show whether a beneficiary has a nearby cardiologist, a preferred hospital, a pharmacy that stocks a necessary medication or transportation to an approved provider.
KFF found that the average beneficiary will have 28 Medicare Advantage prescription-drug plans available in 2027, down from 32 in 2026. The number varies sharply by location. In a metropolitan county, a beneficiary may have several apparently comparable alternatives. In a rural county, the practical choice may be between a narrow network and a much longer trip for care.
A plan’s premium is therefore only one part of the decision. A lower premium can coexist with higher cost-sharing, a narrower network or a larger maximum out-of-pocket exposure. A benefit advertised as transportation assistance or healthy-food support may also depend on detailed eligibility and purchasing rules.
CMS has finalized requirements intended to make supplemental-benefit debit cards more transparent and to link them to covered products and services. Those rules may improve administration, but they do not guarantee that a benefit is easy to use or available when a person needs it.
Drug-price reductions will not remove the need to compare
There is positive news in the 2027 changes. Medicare-negotiated prices for 15 additional Part D drugs take effect January 1, 2027. The redesigned Part D benefit also includes a $2,400 annual out-of-pocket cap for covered prescription drugs.
But lower negotiated prices will not affect every beneficiary in the same way. The practical result will depend on whether a person’s medication is included in the plan’s formulary, which tier it occupies, which pharmacy is used and how the plan applies cost-sharing rules. Medicare advises beneficiaries to check their plan’s drug list and pharmacy arrangements rather than assuming a national price announcement will automatically lower their bill.
KFF also projects that the average premium for stand-alone Part D plans could rise from $34 in 2026 to $51 in 2027 if current enrollees do not switch to lower-premium plans. That makes the enrollment decision more consequential for people who rely on traditional Medicare and separate drug coverage.
Assistance exists, but finding it is another task
Some beneficiaries may qualify for Medicare Savings Programs or Extra Help with prescription costs. CMS’s 2027 landscape materials say only about half of people who may be eligible for Medicare Savings Programs are enrolled.
That gap matters because assistance is not automatic for everyone who qualifies. Beneficiaries may need to provide income and asset information, complete an application and navigate a state or local agency. People with limited English proficiency, unstable housing, disabilities or no reliable internet access may face additional barriers.
State Health Insurance Assistance Programs can help people compare coverage without relying solely on an insurer or broker. During an enrollment season affecting millions of people, however, the usefulness of that resource depends on whether beneficiaries can obtain an appointment or receive help in a language they understand.
What families should check before December 7
Beneficiaries and caregivers comparing 2027 coverage should look beyond the premium and ask:
- Are every current doctor, hospital, laboratory and specialist in network?
- Are all prescriptions covered, and have their tiers or authorization requirements changed?
- Which pharmacies offer preferred cost-sharing?
- What are the deductible, copayments, coinsurance and maximum out-of-pocket limit?
- Will transportation, dental, vision, food or over-the-counter benefits change?
- Is the plan being terminated, consolidated or renewed under a different plan identifier?
- If switching to traditional Medicare, is Medigap available and are guaranteed-issue protections applicable?
- Does the household qualify for a Medicare Savings Program or Extra Help?
Beneficiaries whose Medicare Advantage plan is being terminated generally receive a special enrollment opportunity for Medigap with guaranteed-issue rights, according to KFF. People moved automatically through a consolidation may not have the same federal guarantee if they later switch to traditional Medicare. That distinction can be important for people with significant medical histories.
The system’s definition of choice is changing
Some people will find a better plan or lower costs in 2027. Not every plan termination will produce a medical crisis, and not every benefit change will harm every beneficiary.
But the larger pattern deserves scrutiny. Medicare beneficiaries are increasingly expected to make expert-level decisions about networks, formularies, authorization rules and supplemental benefits every year. The system offers alternatives, but it also transfers responsibility for checking those alternatives onto older adults and the relatives who help them.
That is why the success of Medicare Advantage should not be measured only by premiums, plan counts or enrollment. It should also be measured by continuity of care: whether patients can keep seeing the clinicians who know them, obtain the medicines they take and reach the services they depend on without a new administrative crisis every January.
The first evidence will emerge after January 1, when beneficiaries discover whether their new coverage works in practice. Complaints, denied authorizations, prescription changes, delayed appointments and continuity-of-care requests will tell us more than a national count of available plans ever can.
